A body of mass 50 kg is lifted to a height of 20 m from the ground in the two different ways as shown in the figures. The ratio of work done against the gravity in both the respective cases, will be:\\
Case 1: Vertically upward\\
Case 2: Along the ramp\\
(1) $1:2$\\
(2) $\sqrt{3}:2$\\
(3) $2:1$\\
(4) $1:1$
